.
Print (Date ("L DS of F Y h:i:s A"));
Print ("July 1,". Date ("L", Mktime (0,0,0,7,1,2000));

Example two:

$tomorrow = mktime (0,0,0,date ("M"), Date ("D") +1,date ("Y"));
$lastmonth = Mktime (0,0,0,date (" M ") -1,date (" D "), Date (" Y "));
$nextyear = mktime (0,0,0,date ("M"), Date ("D", Date ("Y") +1);

strftime formats the server's time locally.
Syntax: string strftime (string format, int [timestamp]);
return Value: String
